trans-Bis[bis­(2-methoxy­phen­yl)phenyl­phosphine-κP]dichloridopalladium(II)

The structure of the title compound, [PdCl2(C20H19O2P)2], shows a square-planar geometry for the PdII ion within a Cl2Pd[PPh(PhOMe)2]2 ligand set. The PdII atom sits on an inversion centre and therefore the asymmetric unit contains the PdII atom, one Cl atom and one bis­(2-methoxy­phen­yl)phenyl­phosphine ligand. The trans arrangement of ligands is also imposed by symmetry

trans-Dichloridobis[tris­(2-methoxy­phen­yl)phosphine]palladium(II)

The structure of the title compound, [PdCl2(C21H21O3P)2], shows a nearly square-planar geometry for the PdII atom within the Cl2Pd[P(PhOMe)3]2 ligand set. The PdII atom sits on a centre of inversion and therefore the asymmetric unit contains one half-mol­ecule, i.e. half of one PdII atom, one Cl atom and one tris­(2-methoxy­phen­yl)phosphine ligand

trans-Dichloridobis[tris­(4-methoxy­phen­yl)phosphine]palladium(II) benzene monosolvate

The structure of the title compound, [PdCl2(C21H21O3P)2]·C6H6, shows a square-planar geometry for the PdII atom within a Cl2[P(PhOMe)3]2 ligand set. The crystal structure contains benzene as solvent. The PdII atom sits on a centre of inversion and therefore the asymmetric unit contains the PdII atom, one Cl atom, one tris­(4-methoxy­phen­yl)phosphine ligand and one half of the benzene solvent mol­ecule

Bis[(1,1′-biphenyl-2,2′-diyl)di-tert-butylphosphonium] di-μ-chlorido-bis[dichloridopalladate(II)]

In the title compound, (C20H26P)2[Pd2Cl6], the PdII atom within the hexachloridodipalladate(II) dianion has a square-planar geometry. It resides on a centre of inversion with the asymmetric unit containing half of the dianion and one phosphonium cation. Only weak C—H...π interactions are present in the crystal structure

Di-μ-chlorido-bis{[2-(di-tert-butylphosphanyl)biphenyl-3-yl-κ2C3,P]palladium(II)} dichloromethane disolvate

The asymmetric unit of the title compound, [Pd2Cl2(C20H26P)2]·2CH2Cl2, contains one half-molecule of the palladium complex and a dichloromethane solvent molecule. In the complex, two PdII atoms are bridged by two Cl atoms, with the other two coordination sites occupied by a C atom of the biphenyl system and a P atom, resulting in a distorted square-planar coordination geometry of the PdII atom and a cyclometallated four-membered ring. The Pd2Cl2 unit is located about an inversion center. The planes of the rings of the biphenyl system make a dihedral angle of 66.36 (11)°

μ-Carbonato-κ4O,O′:O′,O′′-bis{[2′-(di-tert-butylphosphanyl)biphenyl-2-yl-κ2P,C1]palladium(II)} dichloromethane monosolvate

The title compound, [(μ2-CO3){Pd(P(t-C4H9)2(C12H8)}2]·CH2Cl2, the first CO3-bridged palladium dimer complex reported to date, was obtained while preparing the Pd0 complex with (2-biphenyl)P(tBu)2. In the crystal, each palladium dimer is accompanied by a dichloromethane solvent molecule. Coordination of the carbonate and chelated phosphane ligands gives distorted square-planar environments at the Pd atoms. Important geometrical parameters include Pd—P(av.) = 2.2135 (4) Å, Pd—C(av.) = 1.9648 (16) Å and P—Pd—C = 84.05 (5) and 87.98 (5)°, and O—Pd—O′ = 60.56 (4) and 61.13 (4)°. Bonding with the carbonate O atoms shows values of 2.1616 (11) and 2.1452 (11) Å for the Pd—O—Pd bridge, whereas other Pd—O distances are slightly longer at 2.2136 (11) and 2.1946 (11) Å. One of the tert-butyl groups is disordered over two set of sites with an occupancy ratio of 0.723 (6):0.277 (6). Weak C—H...O interactions are observed propagating the molecules along the [100] direction
